13 2.0 OPERATION This portion of the manual contains the following sections: Quick Start To use your unit right away, follow the brief instructions on basic operating procedures in this section. Principles of Operation A short introduction to infrared thermometry. Your Portable Infrared Thermometer Describes and illustrates the thermometer s control panel, display, and features. How to Operate A detailed user guide that describes each of the operating modes. It includes descriptions of the RUN, RECALL, SETUP, and Data Logger loops. Data Outputs How to use the analog and digital (RS232) outputs to connect the thermometer to a printer, chart recorder, or computer. WARNING SAFETY Models with laser sighting produce visible laser radiation that may be harmful to the human eye. Be aware of the following: Avoid direct exposure of human eyes to laser light. Eye damage can result. Use extreme caution when operating. Never point the unit at another person. Keep out of the reach of children. Refer to the FDA laser label on the unit for specific information. IMPORTANT 1. If the unit is exposed to significant changes in ambient temperature (hot to cold or cold to hot), allow 45 minutes for temperature stabilization before taking measurements. 2. Do not operate the unit near large electrical or magnetic fields such as arc welders and induction heaters. These fields can cause measurement errors. 3. For the short wavelength units (e.g., 2 µm and below) Avoid taking temperature measurements in bright sunlight. High levels of ambient light may produce apparently valid high-temperature readings when no target is in the thermometer s field-of-view. Raynger 3i Series Operator s Manual 2-1

14 2.1 QUICK START To use your portable infrared thermometer right away, complete the following steps: Note: For complete definitions of your portable thermometer s modes and functions, and for a full explanation on its operation, refer to Sections 2.3 and Point the instrument at the object you want to measure (perpendicular to the object) and pull the trigger. The current temperature (in C or F), the emissivity value, and the maximum measured temperature will be displayed (similar to Figure 2-1). 2. Change the emissivity value to correspond to the material you are measuring by pressing the and buttons. (For example, if you are measuring wrought iron with an 8-14 micron instrument, set emissivity to If you are measuring asphalt, leave the emissivity at the default setting of For other materials and for instruments with other spectral ranges, refer to the emissivity charts in Appendix B.)

15 2.2 PRINCIPLES OF OPERATION An infrared thermometer and the human eye are very similar. An infrared thermometer has a lens that focuses infrared radiation from an object onto a detector. The eye focuses light onto the retina. The detector is stimulated by the incoming infrared energy and produces a signal that is transmitted to the circuitry. The retina is stimulated by incoming light and sends a signal to the brain. The circuitry processes this signal and computes the temperature of the object. The intensity of an object s emitted infrared energy increases or decreases in proportion to its temperature. The higher the temperature of the target, the greater the intensity of infrared radiation. To calibrate a noncontact temperature measurement instrument, the manufacturer uses a blackbody. A blackbody is a perfect emitter because it absorbs and emits all radiant energy but reflects or transmits none. The emissivity value of a blackbody is Figure 2-2 shows the radiant emittance values of a blackbody at various temperatures and wavelengths. Most objects have emissivities that are less than 1.00 but are reasonably uniform at all wavelengths of the infrared spectrum. These are called graybodies. The non-ideal (less then 1.00) emissivity values of different materials can be compensated for, by the emissivity controls, so that accurate temperature readings can be obtained. Emissivity values for many common materials (both metals and non-metals) are listed in Appendix B Blackbody Radiant Emittance (Watt/cm ) C (2730 F) 1000 C (1830 F) 542 C (1000 F) 260 C (490 F) 20 C (70 F) Wavelength (Microns) Figure 2-2: Blackbody Radiation Curves Raynger 3i Series Operator s Manual 2-3

16 2.3 YOUR PORTABLE INFRARED THERMOMETER Portable infrared thermometers measure surface temperatures without touching the surface. They collect the infrared energy radiated by a target and compute its surface temperature. They also compute the running average, maximum, minimum, and differential temperatures and present them on a digital display in either degrees Celsius or Fahrenheit. A digital/analog output allows data recording, instrumentation or process control, and/or remote display of temperature and emissivity. The instrument is battery powered or can be powered by an optional AC adaptor. Internal memory circuits store temperature data for later recall, and a datalogging feature allows you to store up to 100 temperature, emissivity, and alarm readings (valuable for comparative analysis). Figure 2-3 shows the features of the portable infrared thermometer.

To store a temperature reading, pull the trigger all the way in until you hear the tone (the tone signals that the reading has been stored). When you release the trigger, the unit goes to sleep. Control Panel and Display All controls (except the trigger) are located on the control panel. The display shows temperature and setup values, mode and loop status, and operating information. Sighting System Laser or scope sighting is provided with each model. Note: Read the laser warning label before operating the laser. Analog Output Connects the instrument to analog recording/printing devices such as chart recorders and printers. Digital Output An RS232 interface to connect the instrument to a computer or directly to a printer s RS232 port. DC In AC adaptor connection. Raynger 3i Series Operator s Manual 2-5

18 2.4 OPERATION AND CONTROLS This section instructs you in the operation of the instrument. It describes battery and/or AC adaptor installation and the controls and functions of the different control loops and operating modes Battery/AC Adaptor Installation The instrument may be powered by batteries or an AC adaptor. Battery power is supplied by 4 AA batteries. The batteries are located in the base of the handle. AC power is supplied by an optional AC power adaptor (DIN VDE 0551 approved). NiCad batteries can also be used, but battery life will be substantially reduced. Figure 2-3 shows the location of the battery compartment, battery orientation, and the location of the AC adaptor power connection. Table 2-1 shows approximate battery life (for alkaline batteries) for various operating conditions. Table 2-1: Battery Life (Alkaline) CONDITION Laser OFF Backlight OFF Laser ON Backlight OFF Laser OFF Backlight ON Laser ON Backlight ON "Sleep" mode (trigger off) HOURS OF CONTINUOUS USE year Notes: Battery types and brands vary in length of usable life. The values in Table 2-1 are approximate for new alkaline batteries. The instrument will continue to read accurately up to 4 hours after the low battery icon displays if the laser and backlight are off. Remove the batteries if the unit is not used for long periods of time. 220 VAC adaptors must have DIN VDE 0551 approval to be used with IEC Class 2 laser units. 2-6 Raynger 3i Series Operator s Manual

23 Control Loops Each control loop has several modes, which are described in the following sections General Information Before you begin using your portable instrument, you should be aware of the following general operating rules: The instrument goes to sleep (low power consumption, no display, no laser, no backlight) after different times for each loop, as follows: SET Loop (after last button use): 10 seconds RUN Loop (after releasing the trigger): immediately RECALL Loop (after last button use): 10 seconds _ LOG Loop (after releasing trigger): immediately The backlight can be turned on or off in any mode. The laser can be used only in the RUN and LOG loops. The trigger has two stages. The first stage is for measuring temperature. The second stage, when the trigger is pulled all the way in, is for storing temperature values in the LOG loop. The C or F icon flashes when the instrument is measuring temperature in the RUN or LOG loops. It does not flash when values are recalled. You can lock the trigger in the RUN loop and the LOG loop. You must release the trigger to go into the SET or RECALL loops. When you simultaneously press the MODE and ACTIVATE buttons while in the RUN loop, the instrument is reset to the RUN loop factory default settings (stored data is unaffected). In the LOG loop, pressing the MODE and ACTIVATE buttons not only resets the instrument to its LOG loop factory default settings, but also clears all previously stored data. In both cases, the instrument will beep after reinstalling the default settings. Section 3.6 lists default setting for each model as well as non-model-specific default settings and range values. IMPORTANT For the short wavelength units (e.g., 2 µm and below) Avoid taking temperature measurements in bright sunlight. High levels of ambient light may produce apparently valid high-temperature readings when no target is in the thermometer s field-of-view. Raynger 3i Series Operator s Manual 2-11

Note the following: Press the MODE button to change modes. Press the backlight button if a brighter display is needed. Notes on setting Tamb (Ambient temperature compensation) The Tamb icon is activated when the ambient temperature compensation function is active. Targets that have low emissivities will reflect energy from nearby objects. This additional reflected energy is added to the target s own emitted energy and may result in inaccurate readings. In some situations objects near the target (machines, furnaces, or other heat sources) have a temperature much higher than that of the target. In these situations it is necessary to compensate for the reflected energy from those objects. Note that the Tamb feature is disabled if the emissivity is set to To set or change the ambient temperature compensation, complete the following: 1. Go to the RUN loop (pull trigger, press RUN/LOG button, if necessary). 2. Set the emissivity value to Press the MODE button until the mode function indicator displays AVG (average temperature). 4. Pull the trigger and scan across objects and surfaces that face the target. Read the average temperature value in the MODE value display. This is the value to be entered as the reflected ambient temperature in Step 7 below. Release the trigger. 5. Press the SET button (do not pull the trigger) to enter the Setup mode 6. Press the MODE button until TAM shows in the mode function indicator Raynger 3i Series Operator s Manual

The Tamb icon will be displayed indicating that it is active. (Pressing ACTIVATE again turns off the function.) 9. Pull trigger and reset the emissivity to the proper value for the target. You can now take the target s temperature using normal procedures. The current temperature and all computed values, as well as the analog and digital outputs, will now be based on the compensated measurement.

Press the backlight button if a brighter display is needed. 2.5 USING A TRIPOD The instrument is equipped with a standard camera-type tripod mount fitting at the base of the handle. You can set it up for continuous use by mounting it on a sturdy tripod. This allows the instrument to be connected to a digital or analog recording or controlling device (computer, printer, chart recorder, line or temperature controller) to monitor temperatures over long periods of time. Mounting the instrument is easy. Just attach it to the tripod by screwing the tripod s mounting screw into the fitting at the bottom of the handle. You can also connect a digital or analog recording or controlling device to the digital/analog connector (labeled OUT) on the side of the instrument. For continuous monitoring, pull the trigger and press the LOCK button. Note that battery life is shortened by continuous use. If you plan to monitor temperatures over long intervals, you should connect an AC adaptor to the DC IN connector Raynger 3i Series Operator s Manual

36 2.6.1 Digital Output The following sections describe the digital data outputs for each mode Data Output RUN Loop In the RUN loop, the temperature scale, current temperature, emissivity, mode temperature (MAX, MIN, DIF, or AVG), HAL or LAL, a carriage return, and a line feed are sent out at intervals determined by the DOI (set in the SET loop) when the trigger is pulled. HAL or LAL is sent out if the temperature is above HAL or below LAL (when they are activated). Three blank spaces replace HAL or LAL if they do not meet this condition. There are 5 characters for the mode temperature. The fifth character is always a space for MAX, MIN, or DIF. For AVG, the fifth character is a space if the average temperature is 1000 or above. Average temperatures up to use all 5 characters. A total of 29 characters are sent out. Table 2-2 shows a sample output. The headings at the top of the table explain the contents of each column (these are not part of the output).

Emissivity is changed to Data Output SET Loop After entering the SET loop (SET icon activated), setup parameters can be sent out by pressing the SET button again. This information can be sent out at any time while still in the SET loop. Unactivated setpoints are printed in lowercase (e.g., hal) and activated setpoints are printed in uppercase (e.g., HAL). Hi Alarm, Low Alarm, T. Ambient, Temperature Scale, and DOI are sent out and terminated by a carriage return and line feed. A total of 39 characters are sent out. The SET values will be printed any time you press the SET button. Two examples follow: hal 0085 lal 0065 tam 0100 F;DOI 3600<CR><LF> (hal, lal, tam not activated) HAL 0085 lal 0065 tam 0100 F;DOI 3600<CR><LF> (HAL activated) The above lines indicate Hi Alarm = 85, Low Alarm = 65, T. Ambient = 100, the temperature scale is F, and DOI = 3600 seconds. (The <CR> and <LF> do not print; these denote the carriage return and line feed.) Note: DOI does not apply to the SETUP mode. Raynger 3i Series Operator s Manual 2-25

38 Data Output LOG Run Loop When you press the trigger (first stage only) in the LOG Loop, data will be sent out only for those locations that have stored data. The temperature scale, stored main temperature, stored emissivity, stored MAX temperature, location number, HAL, a carriage return, and a line feed are sent out when the trigger is pressed. HAL is sent out if the stored temperature is above or equal to the HAL value for that location, and HAL is activated. Three spaces replace HAL if this condition is not satisfied. A total of 32 characters are sent out. Table 2-3 shows a sample output. The headings at the top of the table explain the contents of each column (these are not part of the output). Table 2-3: LOG Run Mode Output Example S S S S S S S p p p p p p p a a a a a a a C c Main c E for c Emissivity c MAX c Stored MAX c Location c Carriage Line or F e Temp e Emissivity e Value e Mode e Temperature e Number e HAL Return Feed F 0072 E MAX <CR> <LF> F 0095 E MAX <CR> <LF> F 0070 E MAX HAL <CR> <LF> F 0090 E MAX <CR> <LF> Notes (see below) Notes: 1. Current and MAX temperature stored at Location Current and MAX temperature stored, and the emissivity changed to 1.00 at Location Current and MAX temperature stored at Location 7, HAL is active, and the stored temperature is HAL value. When the 2-stage trigger is pulled all the way to store the current and maximum temperatures at Location 7, the current temperature also exceeded the HAL value, which was activated. Therefore, HAL was sent out at the end of the string. Notes: Note that in the above example nothing was stored at locations 2, 3, 4, 5, and 8 through 99, so these locations were not sent out. There will be a pause in printing between locations 1 and 6 and between locations 7 and 100 because the unit is searching through the locations sequentially for stored data. DOI does not apply to the LOG mode Raynger 3i Series Operator s Manual

39 Data Output LOG SETUP Loop After entering the LOG SETUP loop (both the LOG and SET icons are activated), setup parameters are sent out when the SET button is pressed again. This information can be sent out at any time in the LOG SETUP mode. HAL, temperature scale, and the location number are sent out and terminated by a carriage return and line feed. A total of 16 characters are sent out. Go to the appropriate location number in the LOG loop and press the SET button to send out the Hi Alarm value for that location. Activated Hi Alarm locations are uppercase (HAL), and unactivated Hi Alarm locations are lowercase (hal). Only the HAL value at the present location is sent out. For additional HAL values, go to the appropriate location and press SET again while still in any of the two screens in the LOG SETUP mode. To get the LOG SETUP parameters for all 100 log locations, press the SET button for about 3 seconds. Table 2-4 shows a sample output. The headings at the top of the table explain the contents of each column (these are not part of the output).
